Disable 'echo' in the default config, run 'make baseline', then
re-enable 'echo' and run 'make bloatcheck':

The Total bytes value doesn't equal the change in the size of the
binary. The packed_usage and applet_* items are in .rodata and
are counted twice. With this modified bloat-o-meter the size of
named items is deducted from .rodata:

v2: Sections numbered less than 10 were always being omitted from
consideration because splitting "[ 1] .interp" leaves "1]" in
x[1] where the section name is expected. This wasn't a problem
for .rodata (numbered 15 in my testing) but let's fix it anyway.
